Hi! pg_basebackup takes 8 hours. After it is finished, replication slave does not start:
LOG: consistent recovery state reached at 2DE/985A5BE0 LOG: database system is ready to accept read only connections LOG: started streaming WAL from primary at 2DE/99000000 on timeline 1 replikaator@[unknown] LOG: received replication command: SHOW data_directory_mode replikaator@[unknown] LOG: received replication command: IDENTIFY_SYSTEM replikaator@[unknown] LOG: received replication command: START_REPLICATION 2CF/E9000000 TIMELIN replikaator@[unknown] ERROR: requested WAL segment 00000001000002CF000000E9 has already been re replikaator@[unknown] LOG: received replication command: SHOW data_directory_mode replikaator@[unknown] LOG: received replication command: IDENTIFY_SYSTEM replikaator@[unknown] LOG: received replication command: START_REPLICATION 2CF/E9000000 TIMELIN replikaator@[unknown] ERROR: requested WAL segment 00000001000002CF000000E9 has already been removed ... i tried it again and same error occured. How to force replication to start? I increased wal parameters in master to wal_compression=on max_wal_size = 5GB min_wal_size = 4GB # was 80MB wal_keep_segments= 360 # was 180 Will this allow replication to start after pg_basebackup ? According to doc min_wal_size and wal_keep_segments both keep the minimum number of wal segments for replication. Why those parameters are duplicated? Andrus.
